The Monoprice Blackbird™ 4x4 HDMI® Seamless Switching Matrix is an easy to use solution for distributing any of four connected HDMI sources to any of four HDMI displays, in any combination. It supports video resolutions to 1080p@60Hz and includes support for PC control via the RS232 port. The seamless switching feature eliminates virtually all of the switching delay, commonly found in most switch and matrix devices. A front panel button allows you to instantly switch between normal matrix mode and the video wall mode, which splits a single source into four parts for distribution to a 2x2 array of HDMI displays to create a single larger image.

Mine doesn't work with an HDMI extender. Works great for local HDMI displays, and the extenders work great when connected directly to a source. However when I mix both this matrix switch and the extenders, I get audio and video for a few minutes, then the remote screen goes dark. Any chance this is a setting or firmware upgrade somewhere? Do I need a specific extender to make this work?

BEST ANSWER:Try changing resolutions. I had a similar issue and that fixed it for me. I also had an issue with clone vs extended. I could not clone the display, it just went black. When I extended, the display showed up. Adjusting resolution fixed the screen blanking issue I had afterwards.

BEST ANSWER:Thank you for your question. Yes, you would just select the desired input then press the video wall button on the front of the unit or the W button on the remote in the top right. The set up is very easy, the user manual has a diagram showing the setup for the video wall:

can I combine all four sources on one display? I have a 120" projector screen so would like to display up to 4 sources at the same time.

BEST ANSWER:Hello, thank you for your question. While this unit does have 2x2 video wall capability, having a setup as you have described will depend completely on whether your projector supports picture in picture from multiple sources. I hope this helps, and of course if you have any more questions feel free to contact us!

If you are looking this is probably the best cost to value out there for a matrix video wall setup.

This device did almost exactly what I had hoped it would, just an FYI for the rest of you it will only handle passing 2-channel audio. It will not pass anything higher than that. That being said it gets the job done with little lag and great picture. Make sure you have an option on your TV to adjust the screen up/down as I had green lines on the top edge.
